finding a way for changing a 64 bits variable to the 32 bits one

[skaddi]

Hello...

I'm just working on a sensor that for saving some data, it needs some 32 & 64 bits variables.
due to this fact that there is not any type of 64 bits variable in code vision , I should find a way to change that 64 bits in to the 32 bits in order to save the data .

I was wondering if you would help me solve this problem.

I believe floating precision works on CodeVision compiler.

but a float variable again has just 32 bits. so the maximum size for a variable is 32 bits. like Long int or float .
the problem is that my data should be saved in 64 bits.

IAR has a compiler that supports 64 bit I believe

thanks for your help but now I'm working in Code vision and I want to find an exact way to save 64 bits data in it .
I haven't worked with IAR until now but again thanks for recommending it.
